Adding paths inside rails engine

In a application I am working on I have added forms path to app path where I keep my app specific forms. My application searches if file is present inside my app/forms folder or any other forms folder which can be added later. In order this to work I have added: config.paths["forms"] = Rails.root.join('app/forms') to application.rb

I am in the process of transforming part of application to engine. According to what I have found yet this should work:

my_app/lib/my_app/engine.rb

module MyApp   class Engine < ::Rails::Engine     paths["forms"] = File.expand_path("../../../app/forms", __FILE__)     p paths   end end

p paths actually shows that path["forms"] is added to paths, but after that in my application if I do: p Rails.configuration.paths

doesn't include it.

What am I doing wrong?
